Title: Base steel with sanded surface, preparation method and tinplate/tin free steel plate thereof
Inventor: WEI YU
IPC: B21B1/22
Filed: 2022-07-25
Abstract: The present application provides a method for preparing a base steel with a sanded surface, comprising providing a temper mill. The temper mill comprises a first stand and a second stand. The first stand comprises a first work roll and a third work roll arranged oppositely, and the second stand comprises a second work roll and a fourth work roll arranged oppositely. The first work roll and the second work roll are located on the same side. The first work roll is an electrical discharge texturing roll, and the second work roll is a polished smooth roll. The surface roughness of the first work roll is 1.6-2.2 um, and the surface roughness of the second work roll is 0.35-0.75 pm. The base steel is passed between the first work roll and the third work roll, and between the second work roll and the fourth work roll in sequence, so that the sanded surface is formed on a first surface of the base steel. When the base steel with the sanded surface is processed into a necked-in can or an easy-open end after tin plating or chrome plating, the coating at the necked-in and pre-scoring positions is not easily damaged, and has good corrosion resistance.

IPC: E01F15/08
Filed: 1976-09-08
Abstract: The sound-absorbent barrier has corrugations on one or more faces, and is particularly for the reduction of noise generated by road traffic. It is designed for installation along motor-ways and their central reservations and also acts as a crash barrier, absorbing shock loads by stretching in the lengthwise direction. It is built up of components alongside and one above each other, each of box-section and with plates held apart by vertical U-section members between, and the space between the plates can be at least partly filled with filler material. To- allow each component to be mounted directly between the adjacent ones without the use of a post etc, each of the vertical panels (1) has a U-shaped throat formed by the vertical members (10, 11). The base of the throat is formed by the body of the member, while the throat slides form arms covering the corresponding ones of adjacent components (5). They are secured to the latter by fixing devices passing through openings in the arms.

Title: Composite insulating structural floor - uses precast cellular concrete slab as permanent form reinforced concrete beam and slab
IPC: E04B5/36
Filed: 1981-01-14
Abstract: The floor may span up to 9 metres and incorporates permanent soffit forms (10) of a precast lightweight cellular insulating concrete construction.

Title: Producing crystallisation seeding material for water purificn. - by precipitating insoluble calcium salts or phosphate(s) in fluidised bed reactor using particles discharged from reactor after crushing
IPC: B01J23/755
Filed: 1984-04-24
Abstract: The method is intended for producing seeding material to act as crystallisation nuclei for the pptn. of insoluble calcium salts in a fluidised bed reactor used for water purificn..

Title: Electrically driven vehicle with two motors - has switching circuit to select braking and drives
IPC: B60K1/00
Filed: 1985-12-18
Abstract: The 12 volt battery supply is connected to the switching circuit (1) via a fuse (25A), a battery condition test indicator (S5, L1 to L3) and an ammeter (A). The current passes through a switch (56) which reverses the polarity of the supply and hence the direction of travel. The other four switches (S1 to S4) control the connection of the supply to the two motors (M1,M2). In the 'rest' position, both motors are short-circuited and thus act as dynamic brakes. When the first switch (S1) is operated, one motor (M1) is open circuited reducing the braking power. When the second switch (52) is operated, the motors are connected in series to the supply. When the third switch (53) is operated, the motor (M1) is supplied with full voltage while the other (M2) idles. The fourth switch (S4) connects both motors in parallel to the full voltage giving maximum drive power.

Each circuit consists of a voltage detector, current detector, protection device and an electronic circuit breaker. The protection device can be a resistance and Zener diode or a spark-gap in parallel. The impedance switch can be operated by either current detector.

Title: Sepg. ammonia from liq. manure - by volatilisation and reaction with inorganic acid, giving useful ammonium salt
IPC: C02F1/58
Filed: 1989-06-22
Abstract: In sepn. of NH3 from liq. manure, to render this low in NH3, the manure is transferred to an NH3 volatilisation chamber, where the NH3 is liberated from the liq. phase and is transferred, in the gaseous state, to a chamber contg. inorganic acid, where the NH3 is converted to a soln. of an NH4 salt, suitable for use as inorganic fertiliser. The treated air stream is released to the amtos., opt. after further treatment. The NH3 is pref. chemically volatilised (by addn. of a base, partic. CaO) and/or mechanically (by raising the effective specific surface of the manure), and the NH3 gas is passed into the chamber contg. acid by an air stream led into the volatilisation chamber. The effective surface is raised by stirring and/or spraying the manure, or leading it over slightly inclined plates into the volatilisation chamber, or by means of a continuous air stream. A conc. acid is used, esp. conc. HNO3. The gas stream leaving the acid chamber is treated with an adsorbent and/or absorbent, pref. an aq. suspension of neogen, and released into the atmos.

Patent NL-9202029-A (NL)
IPC: B29C35/02
Filed: 1992-11-23
Abstract: Method for producing a deformed pipe liner, starting from a tubular starting section (1) made of thermoplastic material which has an annular crosssection. According to the method, the tubular section moving out of an extruder is moved along between shaping (3) and supporting means (16) for the production of an essentially C-shaped deformation. The inside of the wall of the starting section is kept at a higher temperature than the outside of the wall, at least during the deformation of the starting section. The temperature of the inside of the wall is preferably kept lower here than the crystalline melting temperature of the plastic material.
Patent NL-9301971-A (NL)
Title: Microfiltration membrane, and method for fabricating such a membrane
IPC: B01D69/02
Filed: 1993-11-12
Abstract: The microfiltration membrane comprises a support with holes and a membrane layer provided with pores having a pore size of between 0.005 μm and 50 μm. The membrane can be fabricated simply and reliably by a relatively thin layer being applied initially to the support, for example with the aid of a suitable vapour-deposition or spin-coating technique, followed by perforations being produced in the membrane and holes being produced in the support, for example by means of etching with the aid of photolithography or a printing technique. A membrane fabricated in this way is highly suitable for separation of biological cells. A membrane layer having a thickness less than the diameter of the perforations is particularly suitable for separating delicate (vulnerable) particles or stress-sensitive cells. <IMAGE>
